What is the formula for trinomial?
The general form of quadratic trinomial formula in one variable is ax2 + bx + c, where a, b, c are constant terms and neither a, b, or c is zero. For the value of a, b, c, if b2 – 4ac > 0, then we can always factorize a quadratic trinomial.
What is trinomial example?
A trinomial is an algebraic expression that has three non-zero terms. Examples of a trinomial expression: x + y + z is a trinomial in three variables x, y and z. 2a2 + 5a + 7 is a trinomial in one variables a. xy + x + 2y2 is a trinomial in two variables x and y.

What is the product and sum of a trinomial?
The Product Sum method of factoring we use on trinomials (ax2+bx+c) with the value of a=1. This is the method that is probably used the most. example: x2+7x+12. The product is the a value times the c value.
How do you multiply polynomials step by step?
Step 1: Multiply the first term of each binomial. Step 2: Now multiply the outer term of each binomial. Step 3: Once this is done, now multiply the inner terms of the binomials. Step 4: Now the last terms are multiplied.
What are the rules of trinomials?
The rules are as follows: If all terms of the trinomial are positive, then all terms of the binomials will be positive. If the last term of the trinomial is negative but the middle term and the first term are positive, then one term of the binomial will be negative and the other will be positive.
What are the rules in multiplying Monomial and polynomial?
To multiply a polynomial by a monomial, use the distributive property: multiply each term of the polynomial by the monomial. This involves multiplying coefficients and adding exponents of the appropriate variables.
